    Im looking at going the big bore caliber route in a 10" barrel for one of my SBRs.
    Anyone have any input on this . Im leaning towards the .458 socom over the .50 Beowolf and the .450 Bushmaster . Any input would be greatly appreciated

    Very expensive unless you reload but tons of fun and hits like a train wreck(458 socom) no experience with the other two but aa makes the 6.5 Grendel as well and that thing is a hoot with great ballistics so I would imagine the 50 would be good as well

    i would recomend the socom. simply huge bullet selection unlike the 50's which limit you to pistol bullets, while effective there just are not as wide a variety.

    the socom has the same ballistics as the 45-70.

    the socom uses standard nato ar15 mags. pmags have some difficulty with it. the rest use either proprietary mags or modified nato mags.

    i use 30 and 20 round milsurps with mine

    I have experience with socom and it is great to work with. You should go for it.

    I am in the process of building a 458 SOCOM for pig hunting etc. After a bit of research I chose the 458 SOCOM because it seemed as if everything was more readily available and the performance was what I was looking for. SBR Ammuntion usually has 458 ammo in stock. Wilson combat is now selling rifles and components. RRA has a wide selection of rifles. I am using the Wilson Combat upper, lower and barrel kit in my build. Hornady, Lee & Redding produce reloading dies. There are lots of options for bullets. Brass is a little hard to come by, but I got mine by having Starline notify me when it was available. Midway is taking backorders for 458 SOCOM brass as of 5/29/14.

    I have my upper complete. Originally I was going to just exchange uppers, but after completing the upper, I decided to buy a lower receiver and finish out the entire rifle. As to the original question in this post, I don't know about using the 458 SOCOM in a 10 inch barrel SBR. The kit I bought from Wilson has a 16 inch barrel with a carbine length gas tube and an adjustable gas block. Wilson also offers a 14.7 inch barrel kit, but I have not seen a 10 inch barrel for sale. However teppojutsu.com has a photo of a 8.5 inch upper, so I suspect that they know of a source for barrels. I'd be interested in knowing how you proceed.

    Marty terweem(sp) at teppojutsu invented it so his info is most likely correct

    After a little more research it turns out that Tromix sells both 10.5 and 12 inch 458 socom barrels.
